To all whom it may concern.- 7 I Be it known that I, HEINnIcH MAYnn, acitizen of the German Empire," and residing at Arbon, Switzerland, haveinventedrcertam new and useful Improvements in Plate- Springs forVehicles, of which the followthe bodies of vehicles.

A primary object of this invention. is to obviate a defect which hasbeen attached to plate, laminated or leaf springs of all kinds employedhereto-fore for the suspension of This defect is that when the springsare flexed, the stiffness thereof increases toward the end of suchflexion. If thelone spring ofa pair of carsprings resting on an axle isfiexed more than the other, owing to the shortening of the distancebetween the two springs which are located opposite one anotherthatspring which is flexed most is twisted in addition, so that the samemust bend inward and consequently the above mentioned stiffnessincreases, quite aside from the considerable additional injuriousstresses produced thereby. The problem arising in consequence of thisdefect can be solved in vari- According to this inveneion the plate,laminated or leaf springs in question are guided in such manner that itis impossible for them to twist.

To these ends, the invention consists. in the construction, arrangementand combination of parts described hereinafter and pointed out in theclaim. p

In the accompanying drawings, Figures 1, 2 and 3 are side elevation, endelevation and top plan view, respectively Two plate, laminated or leafsprings a, 6 arranged vertically one above the other are connected,'onthe one hand, to the axle support or steeringjswivel c and, onjthe otherI hand, to the frame (Z of the vehicle in a suitable manner but so,however, that a continuous axle which connects the'two wheels togethercanbe dispensed with; ltis iLdVlS- able that such an axle be dispensedwith in sion of the through axle has,

of this arrangement becomes much as the same affords the possibility oforder with certainty to avoid the abovementioned shortening of thedistance betweenthe springs and the defects connected therewith. In thisarrangement it is only essential thatthe central bearings e ofthe twosprings be rigidly connected together which, inthis illustrativeembodiment, is effected by casting them in one piece with the axlesupport or steering swivel. The omisin addition, other technicaladvantages which become apparent particularly in motor-cars for the anadvantage that the platform or bottom of thevehiclc can be locatedlowerjdown so that its distance from the groundis reduced. The loadingof aeroplanes on cars ismateriallyfacilitated in this manner. Further,by simply removing the shacklebolts the wheels can be lifted about theopposite point of suspension asa I can be lowered on to the ground,whereby a similar advantage when traveling in the country the advantagebeing able to pass under low railway bridges andthe like, whereasthe'top of a taller ve- 1 I j I hicle might abut against the same.
